APPARATUS FOR DISPENSING HYDROCARBON'LIQUIDS.

Specification of Letters Patent. f Patented March 23, 1909.

Application filed December 10, 1907. serialflo. 405,851.

To all whom it may concern: I

Be it known that I, JOSEPH BQ'EVANS, a citizen of the United States, and a; resident of Selma, in the county of Dallas and State of Alabama, have invented a new and Im proved Apparatus for Dispensing Hydrocarbon Liquids, of which the following is a full, clear, and exact description.

This invention is an improvclnont in dispensing apparatuses for hydrocarbon liquids, of the character set forth in my co-pending applications SeriallyNumbered 395,497 and 395,498, filed October 2, 1907. I

The object of the present invention is to provide, in connection with a suitable reservoir or tank supplied with a liquid pressure, aswater, a gasolene tank for measuring 011" and discharging a predetermined quantity of the hydrocarbon liquid, the same being introduced into the measuring tank by the passage of the water therefrom into the reservoir, and being expelled by the water pressure in the reservoir;

Reference is to be had to the accompanying drawings forming'a part of this specification, and wherein is represented in central vertical section, one embodiment of my improved dispensing apparatus.

The apparatus includes a reservoir 1 of suitable capacity, provided with a fillingplug 2, to which a hose may be attached for introducing gasolene or other hydrocarbon liquid into the reservoir. Leading into the reservoir at or near its bottom is a water pressure supply pipe 3, ordinarily connected with the "city water mains, and having a controlling-valve 4 by whichthe water pressure may be cut oil from the reservoir when desired. The introduction of the water into the reservoir maintains it at all times ina filled condition, whereby a free surface of the gasolene will not be presented, which avoids evaporation and the accumulation of gas in the upper portion of the. reservoir,

and thus minimizes the waste. from this source, andthe danger of explosion.

Leading from or near the bottom of the reservoir to the sewer or other suitable point of discharge, is a pipe 5, having a controlling valve 6; the passage of the liquid from the reservoir into this pipe being controlled by a float-valve 7, inclos'ed by a cage 8, the valve being of such specific gravity as to buovantly rise from its seat in water but readily sink to its 'seat in gasolene or other like liquid, and prevent its flow through-the pipc'5; this valve also forming a feature of my inventions hereinbeforc referred to,

Preferably arranged above the reservoir 1 is a measuring tank 9, having the graduated transparent gage 10 located at the side thereof, and provided with a commtnication at or near its bottom, with the lower portion of the reservoir, through the pipe 11.; this communication being controlled by a valve 12. A second communication between the reservoir and the measuring tank is effected by a pipe 13 leading from the top or upper portion of the reservoir to a point near the top of the measuring tank; this pipe also having a valve 14 for controlling the communication between the reservoir and measuring tank of these points.

, Connecting with the upper portion of the measuring tank is a valve-casing 15, of the character embodied in my co-pending applications referred to, the said casing inclosmg a float-actuated valve 16, which sinks andthe same up to the fillin -plug, at which time the water is cut off. T 1e barrel or other receptacle from which the gasolene or other hydrocarbon liquid is en plied to the reservoir is connected to t e filling opening by the attachment of a hose orother suitable conduit. B then opening the valve 6 the water will fi bw to the sewer and draw the gasolene into the filling-plug until the level of the .gasolene reaches the valve 7, which will automatically out off and prevent the further flow through the pipe 5. The valve 6 is then closed, and the valves 4 and 18 opened, permitting the water to pass into t e reservoir u through the pi e 1 1 into the measuring tanlz, which when fiqled, the said valves 4 and 18 are again out off. The apparatus is, at this time, in condition for measuring off and dispensing the hydrocarbon liquid, this being performed by opening the valve 14, whichpcrmits the flow of the gasolene through thepi e 13 into the measuring tank as the water ows therefrom under the action of gravity through the pipe 7 back into the measuring tank to take the place ofthe gasolene expelled. In this man ner the dispensing of the hydrocarbon liquid may be repeatedly carried on while=both the reservoir and the measuring tank are kept in a filled condition. a 4

The arrangement and construction of the ap aratus w 'le being the preferred practical em odiment of my iIlVBDtlOIl, the same may nevertheless be modified in particulars without departing from the nature of the invention as defined in the claims annexed.

Having thus described my invention, I claim as new and desire to'secure by Letters Patent:

'1. The combination of a reservoir adapted I to contain a hydrocarbon liquid, a tank, means forintroducing under pressure into the reservoir, li uid of higher specific gravity than the hy ocarbon liqui means providing communication between the reservoir and tank for the passage of the hydrocarbon liquid, and means for forcing the hydrocarbon liquid from the tank in the reservoir.

2. The combination ofa reservoir, a tank,

by the pressure a pipeleading from the upper portion of the reservoir'to the upper. portion of the-tank, having a controllmg'valve, a pipe leading from the lower portion of the reservoir to the ling va ve independent of the first mentioned controlling valve, and awater pressure su ply leading into the lower portion of-'t e reservoir independent of said tank.

In testimony whereof I have signed my 7 lower ortionof thetank, having a controlname to this specification in the presence of two subscribing witnesses.
